Anthurium plant named ‘Rijnpilo’

ABSTRACT

A distinct cultivar of Anthurium plant named ‘Rijnpilo’, characterized by its upright and somewhat outwardly spreading plant habit; dark green leaves; dark pink-colored spathes with salmon pink-colored spadices that are positioned upright and beyond the foliage on strong and erect scapes; and good inflorescence longevity.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the name ‘Rijnpilo’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new freely flowering Anthurium cultivars with strong roots, dark green leaves, attractive spathe color, and good inflorescence longevity.

The new Anthurium originated from a cross by the Inventor in 1996 of the Inventor's proprietary Anthurium andreanum selection code number 90-026 as the female, or seed, parent with the Inventor's proprietary Anthurium andreanum selection code number 95-003 as the male, or pollen, parent. The cultivar Rijnpilo was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in April, 1998.

Asexual propagation of the new cultivar by tissue culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the cultivar Rijnpilo. These characeristics in combination distinguish ‘Rijnpilo’ as a new and distinct cultivar:

1. Upright and somewhat outwardly spreading plant habit.

2. Dark green leaves.

3. Dark pink-colored spathes with salmon pink-colored spadices that are positioned upright and beyond the foliage on strong and erect scapes.

4. Good inflorescence longevity.

The new Anthurium can be compared to the female parent, the selection 90-026. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the selection 90-026 in the following characteristics:

1. Plants of the new Anthurium are bushier than plants of the selection 90-026.

2. Plants of the new Anthurium have larger leaves than plants of the selection 90-026.

3. Spathe color of plants of the new Anthurium is darker than spathe color of plants of the selection 90-026.

The new Anthurium can be compared to the male parent, the selection 95-003. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the selection 95-003 in the following characteristics:

1. Plants of the new Anthurium have smaller and more durable leaves than plants of the selection 95-003.

2. Spathe color of plants of the new Anthurium is lighter pink than spathe color of plants of the selection 95-003.

The new Anthurium can also be compared to the cultivar Red Love, disclosed in U.S. Plant Pat. No. 11,005. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the cultivar Red Love in the following characteristics:

1. Plants of the new Anthurium have more rounded leaves than plants of the cultivar Red Love.

2. Plants of the new Anthurium have thicker and more rounded spathes than plants of the cultivar Red Love.

3. Spathe color of plants of the new Anthurium is pink whereas spathe color of plants of the cultivar Red Love is red.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Anthurium.

The photograph on the first sheet comprises a side perspective view of a typical potted plant of the cultivar Rijnpilo that was about 38 weeks old.

The photograph on the second sheet comprises a close-up view of a typical inflorescence and leaves of ‘Rijnpilo’.
